AUXILIARY PRINTING ATTACHMl-INT FOR CYLINDER PRINTING-PRESSES. i

T alt whom it may concern:

Be itknown that I, ASA P. Bnooxs, a citizen of the United States, residin at New Ulm, in the county of Brown an State of Minnesota,- have invented certain new and useful Improvements in Auxiliary Printing Attachments for Cylinder Printing-Presses; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has for its object to provide an auxiliary printing attachment or device for cylinder printing-presses, and is especially 'ected to the provision of an improved means for printing in colors (one or more) on sheets of paper that are subsequently to be printed in the usual way by the press.

To theabove' ends the invention consists of the novel devices and combinations of devices hereinafter described, and defined in the spending to places left mg devices.

. an enlarged detail, with claims.

Theso-called auxiliary printing device is adaptedfor application to cylinder-presses of standard construction, and it comprises a so-called printing-cylinder that cooper-.

ates with the tympan of thepress-cylinder to print upon sheets of paper carried by said tympan letters, words, figures, or other matter within a certain space or spaces corretherefor 1n the typeforms. These primarily-printed sheets are delivered in the regular manner to the types forms and thence from the press.

The improved printing attachment is illus trated in the accompanyin drawings, where in like characters indicate ike parts throughout the several views. Referring .to the drawings, Figure 1 is a view 'mfront end elevation, showing a portion of the cylinder-press having applied thereto one of my improved auxiliary print- Fig. 2 is a side elevation of the partsshown in Fig. 1. Fig. 3 is a vertical section taken on thelinew m of Fig. I. Fig. 4 is an enlarged section taken througha portion of the auxiliary printing-cylinder on the line afar of Fi 1. Fig. 5 is a complete section throu h t e auxiliary printing-cylinder, taken on t e line :0 x of Fig. 1;. and Fig. 6 is parts broken? away,

taken in section approximately on the line Specification of Letters Patent.

ard construction, and of the parts of which it is necessary to note only the frame 1 the cylinder '2, and the reciprocato plate 3. The cylinder 2 has the usual perip eral tympan 4, and the plate 3 carries the type-forms 5. The character 2 indicates a sheet of paper carried byand held on the tympan 4by the usual clamping devices (not shown) and which, under a rotary movement of thecylinder 2 in the direction of the arrow marked thereon in Fig. 2, is carried against the typeforms 5 in the usual way. The cylinder 2 just forward of the paper sheet 2, is formed with a shallow de ression or channel 2, that preferably exten s entirel across or from end to end of the said cylin er.

Rigidly secured to forwardly extended arms 1 of the sides of the frame 1 is a air of upwardly-extended brackets 6, which at their upper extremitiesare formed with elongated heads 7.

The numeral 8 indicates a non-rota shaft or spindle (as shown, tubularin form) t at extends transversely of the press in front of the cylinder 2, with its ends seated in the heads 7 of the brackets 6 and rigidly but adjustably securedthereto by opposmg set-screwsQ. v

The auxiliary printing-cylinder is rotatively mounted on this shaft or spindle 8. This so-called auxiliary printing-cylinder is made up chiefly of a pair of laterally-spaced heads 10, that are rigidly connected and slpaced apart by tie-bars 11, 12, 13, and 14. v

. his cylinderis therefore partly open; but it must be formed'with a segmental peripheral plate or portion 15, suitable to constitute a bearing and support for the stencil. As shown, this segmentalste'ncil-sup ort is perforated to constitute the outer wa lof an inkreservoir 16 that is rigidly but detachably secured to the tie-bars 13 and 14 and is pro-' vided at its inner" ortion with a cap-closed filling-nipple 17 'l he said plate 15 also preferably projects at its is set into the heads 10 of the auxiliary printitug-cylinder, so'that the said cylinder-heads orm the stencil and stencil-supporting plate 15.

Over the perforate segmental plate 15 is ends and overlaps, but

bearings to relieve the pressure from t tightlystretched-a piece-orweb of cotton flan nel 18,-and over this web of cotton flannel the stencil 19 is tightly stretched. The lower end of the cotton flannel web 18 is la d between the fixed bar 14 and a loose clamping-bar 20,- and the lower end of the stencil 1 9 1S clamped between the said bar. 20. and a iro .
